Series Vertical version
R: If there are ballbearings
*DN discharge nozzle [“]
D: If there is extra gear length
Helical gear pumps
1. Fields of Application
RC pumps are used for pumping viscous and with lubricating properties liquids without solids in applications such as:
• Marine industry: motor lubrication, fuel feed, fuel transfer and lub-oil transfer.
• Oil: mineral and vegetable oils, oil derivates, greases and additives…
• Petrochemical industry: liquid polymers, viscous solvents, emulsions, adhesives, fuel oil, diesel oil…
• Chemical industry: liquid soap paste, soya oil, glycerine,..
• Paint and lacquer industry: binders, colouring matters, solvents, textile dyes…
2. Operating Data
50 Hz 60 Hz
Capacity, max. m3/h 78 94 Head, max. m 100 100 Operating temp., max. ºC 80 80 Operating pressure, max. bar 10 10 Operating speed, max. rpm 1500 1800
For any specific application beyond these limits, please consult KSB ITUR. All data given in this document are for fully standard construction
3. Design
Double-gear pump, self-priming (1), with in line suction and discharge. Pump casing with adjustable automatic relief bypass valve. Three types:
- Horizontal (sizes from R1 to R4) - Vertical (sizes from R1 to R4) - Close coupled (sizes RC-00 and RC-01)
Close coupled Horizontal Vertical (RCV)
(1) with siphon type pipe installation
4. Designation
RC V - 2 R D
*Except RC-00 which has a nozzle of ¾” and and RC-2 / RCV-2 with 1 ½” nozzle

6.1 Shaft seal Mechanical seal is supplied as standard for biggest sizes. For RC-00 and RC-01- shaft seal is by means of several lip seals.
6.2 Driv e IEC frame electric motor.
6.3 Bearings / Lubrication The RC-00 and RC-01 size pumps do not have independent friction bearing bushes and its upper shaft supports on the motor bearings.
In the models RC-1, RC–1 ½ and RC–2, the shafts and gears are supported by removable friction bearings housed in the side covers.
On the models RC-2R, RC–2RD, RC–3R and RC–4R, they are supported by ball bearings, housed in the intermediate support.
In all cases the bearings are lubricated by the pumped fluid..
6.4 Coupling Flexible, rubber plug type coupling for all pump sizes, except for RC-00 and RC-01, that are close coupled type.
Coupling guard: Metallic protections are supplied as standard.
6.5 Base Plate The horizontal pumps, from RC-1 to RC-4R sizes, can be supplied on a base plate or bare shaft.
Base plate: of steel, welded or U-rails for complete unit (pump and motor).
6.6 Safety valve All the pumps include an adjustable bypass valve for internal safety.
Direction of rotation Fixed as standard. If customer wants to change the direction of rotation of the gears and thus the the direction of pumped fluid, contact KSB ITUR for feasibility since modifications to standard configuration pump must be carried out.
